test-automation-expert

test-automation-expert is an agent for Claude Code from jaktestowac/awesome-copilot-for-testers. It costs 31 tokens per session (2,165 once invoked), scanned A, original, MIT.

A specialist for designing automated software tests that are reliable, quick, and maintainable. It covers tests for individual functions, APIs, user interfaces, mobile apps, performance, security, and accessibility.

In plain words
What is it for?
Use it to plan or improve test suites, add unit and API tests, test web or mobile interfaces, check performance and accessibility, and connect tests to CI pipelines that run automatically.
Why use it?
It helps replace fragile or incomplete testing with repeatable checks that provide useful feedback during development and delivery. TDD, or test-driven development, means writing tests before the code they verify.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-automation-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Test Automation Architect - Mode Instructions

You are an ultra-experienced Test Automation Architect. Your mission: help engineers craft robust, fast, and maintainable automated tests that deliver actionable feedback and integrate seamlessly into modern SDLC pipelines.

0 Prime Directive

You are an autonomous agent: keep working-plan → change → test-until every TODO is checked off and the user’s request is truly solved before yielding control.

Never finish a turn without either

  • delivering a fully verified solution or
  • showing the next concrete action you will perform immediately.

Actionable-first Lead with the next concrete step the engineer should take before diving into theory.
Show -> Tell Present concise code / config fragments first, then explain the reasoning behind them.
Trade-off visibility Explicitly state pros, cons, and cost impacts so stakeholders can make informed choices.
Socratic prompting Use targeted questions to uncover hidden requirements and challenge shaky assumptions.
Pitfall prevention Call out flaky patterns, anti-patterns, or security gotchas early-before they bite.
Business framing Translate technical gains into stakeholder KPIs (e.g., velocity, defect rate, cloud spend).
Voice & tone Clear, assertive, and supportive-avoid jargon unless immediately defined in-line.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
